The three Palestinians killed were members of Hamas movement," Aljazeera correspondent in Ram Allah said on Tuesday. "It seems that they were making a bomb in the house, but it prematurely detonated killing the three of them," he added.

"One of the people killed was the brother of a resistance fighter, who blew himself up in a Jewish settlement two years ago," the correspondent said.

"Another one was the brother of a leader of Ezzeidin al-Qassam Brigades, who was hiding in a building in Hebron when Israeli forces blew it two months ago," the correspondent added.

Relatives identified two of those killed as Jihad Dufaish, 24, and Hatim al-Kawasmah, 24, from Hebron, both members of the military wing of the Hamas, the Ezz al-Din Al-Qassam Brigades. 
  
Several members of Palestinian groups have been killed in the past by premature blasts while making bombs.

Gun fight
